In 2013, Park lost the role of Nicki in the sitcom Undateable to Briga Heelan. Heelan had originally been cast in the role, but was believed to be unable to continue when her sitcom Ground Floor was renewed for a second season. The part was recast with Park, however when Heelan's schedule was adjusted to allow her to appear on both shows, Heelan took back the role.[3]

Park created a band with singer Codi Caraco called Frank and Derol, in which she formerly sang and played bass guitar.[5] The girl band also includes pop star Miley Cyrus's older half-sister, Brandi Cyrus.
